The "Umbrella" singer, who may need plastic surgery, was set to throw her own do on the 20th. Rihanna's rep has also confirmed the cancelation of her Jakarta concert which was scheduled for this Thursday. Police sources said she suffered “horrific” injuries after Brown allegedly punched her in the face in LA on Sunday.

Cops have also revealed the nature of the 911 call that was made in the wake of the attack. Chief investigator Detective DESHON ANDREWS said: "It mostly recorded the sound of a screaming woman."

Rihanna is said to be helping police with their investigation and her grandmother, CLARA BRATHWAITE, has reassured fans that the "Umbrella" hitmaker is doing fine. She told Barbados newspaper The Daily Nation: "I don't want people to worry. Rihanna is fine and she is doing well."
